Find a job where you're not yelled at. Do you work double shifts every day? You can try meal prep.

>how appealing shopping for all those things

Frozen vegetables? Uhh Oatmeal? Wh-Where??

>then spending another hour preparing them

I have a feeling you have little experience in cooking. Microwave black beans in a bowl and put salsa on top. Tada, 1 minute! Scrambled eggs with spinach, 5 minutes.

With your defeatist attitude, life sounds like one big chore.

But I have some empathy, for people who don't have the leisure I have. For instance, I have sympathy for folks who want hot prepared complex food without spending the hour to make it. Nobody imitates a Big Mac or fried chicken sandwich in seconds. Eating oatmeal at home after a hard day is very far from my idea of a good life.

And nobody should dare try. That's toxic crap that'll make you depressed, tired, and unhealthy. Please don't tell me how difficult it is to ball up some ground beef and flick it on a stove top.

Oatmeal is just a grain. https://www.loveandotherspices.com/5-savory-oatmeal-recipes/
